@Raj ji Yes, Symlinks are preferred to tweaking the py codes !!! How I quickly analyzed the first pointer was " parent directory /usr/hdp/2.6.3.0/hive/conf doesn't exist" this by experience is a symlink which points to the configuration files. So without that symlink access to the conf files you can't start the WebHcat server ... View more
